Packard Performance Billet Positive Locking Intake Plenum and Manifold for Yamaha YXZ

This plenum locks and seals the plenum to the throttle body and head.  No more pushing off throttle bodies and plenums under boost.  These have been proven and 50+psi and over 700WHP.  Definitely a must for anyone planning on running over 10psi of boost to their YXZ.  This can also be used on an N.A. YXZ with up to 15Hp gained due to optimal flow and design.  The plenum inlet is positioned vertically on the car.  We do offer various angles of plenums to work with different needs.  Please call for various inlet angles.
